I suspect we're not properly initializing some of the core99 PMU
registers for "no power management". In the case of closing the lid,
there's an "environment interrupt" which signals when the lid closes;
my theory is that we leave the environment interrupt enabled (I don't
think we program the PMU interrupt register at all) and then get an
interrupt we don't expect.
